feat: mobile UAT test enablement - Android automation server + host abstraction

[dangershony]

Summary

Enables running the existing UAT test suite against a USB-connected Android device, driven over adb and the in-app automation server.

Status: Work in Progress

The core infrastructure is in place and smoke-tested, but Android UAT is not fully stable yet. Known issues:

• adb connection drops: Samsung devices can lose USB connection after am force-stop, requiring adb server restart. The start-uat.ps1 script handles this with wait-for-device, but it is not 100% reliable.
• APK deployment friction: Fast Deployment can fail on some devices; may need -p:EmbedAssembliesIntoApk=true.
• Item 4 not done: Mobile-variant assertions/timing (PageSize 4 vs 12, SectionPanel visibility) have not been tuned yet.
• Multi-profile tests: Only the first host uses Android; remaining hosts fall back to desktop. Not yet tested in mixed mode.

Full end-to-end CreateProjectTest has not been run successfully on Android yet, only smoke-level validation (health check + section navigation).

What is implemented

Item 1 - Lifetime-agnostic window resolution:

• AutomationRoot.cs: resolves visual root via TopLevel on all platforms
• All flow helper signatures changed from Window to TopLevel (~45 call sites)
• NavigateToAsync: detects missing DesktopSidebar, drives ShellViewModel directly on mobile

Item 2 - AndroidTestHost:

• Simple connect-only host (no adb management from C#) that polls /health on a pre-configured port
• start-uat.ps1 script handles device setup (setprop, launch, forward)

Item 3 - Config injection:

• DebugTestConfig.cs (#if DEBUG): reads debug.angor.* system properties via Android JNI, maps to ANGOR_* env vars before DI builds
• ProfileNameResolver: falls back to ANGOR_PROFILE env var

Item 5 - Security gate:

• Android automation server now requires ANGOR_TEST_API=1 (was unconditional in Debug builds)
• Binds to loopback only (was IPAddress.Any)

Host abstraction:

• ITestHost interface + TestHostFactory set ANGOR_UAT_HOST=android to switch all tests
• All 9 test files updated to use TestHostFactory.LaunchAsync

Verification

• CreateProjectTest passes on desktop (no regression)
• Android smoke check: health + navigation to all sections (Settings, Funds, Find Projects, My Projects)
• All projects build: App, App.Android, App.Test.Uat (0 errors)

How to use (Android)

# 1. Deploy Debug APK
dotnet build src/design/App.Android/App.Android.csproj -t:Install -f net10.0-android -c Debug -p:AndroidAttachDebugger=false

# 2. Start automation server on device
./src/design/App.Android/scripts/start-uat.ps1

# 3. Run tests
$env:ANGOR_UAT_HOST = "android"
dotnet test src/design/App.Test.Uat/App.Test.Uat.csproj -c Debug
